DEVICE FOR CONVERTING MO-TION.

SPECIFICATION forming part of Letters Patent No. 227,707, dated May 18, 1880.

Application filed April 6, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. TowNLEY, of Tompkins, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Devices for Convertin gReciprocatin g into ltotaryMotion and 1 do hereby declare that the following is afull, clear,

top plan, and Fig. 3 is a front view.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to devices for converting reciprocatinginto rotary motion; and it consists in certain improvements in the construction of the same, which will be hereinafter fully describrd, and particularly pointed out in the claim.

In the annexed drawings, A represents a vertical reciprocating rod, which may be the pitman or connecting-rod-of a Windmill, and for which suitable bearings are provided in cross-pieces B, connecting the upper and lower ends of uprights G D, arranged, respectively, in front of and behind the reciprocating rod A. E F are levers, pivoted to the uprights G D, respectively, and extending in a forward direction, their extreme outer ends being preferably, but not necessarily, an equal distance from the front upright. The said levers are connected by short cranks G G with the recipro'cating rod, by the motion of which an oscillating motion is thus imparted to the levers.

In suitable bearings just below the front ends of the levers E F, and transversely there 0 to, is arranged a shaft, H, carrying adrivewheel, I. Chains or cords'J J, attached to the outer ends of the levers, are wound in the same direction round the clutch-pulleys K K upon shaft H, and have weights L L attached to 5 their lower ends. By this' construction, when the levers are oscillated by the reciprocating motion of rod A the cords J are alternately loosened, thus being unwound by the weights L, or tightened, thus causing a steady rotary motion to be imparted to shaft H by the upward movement of the levers.

Owing to the general construction of the mechanism, as described, there are no deadccnters to be overcome.

The construction of the device is simple and inexpensive, and the motion of the parts in operation easy and continuous.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States As an improvement in devices for converting reciprocating into rotary motion, the uprights '0 l), cross-pieces B B, reciprocating rod A, levers E F, cranks G G, cords J J, hav- I ing weights L L, and shaft H, having drivewheel 1, all combined, arranged. and operating substantially as and for. the purpose set forth.

In testimony that I claim the foregoing as 7 my own I have hereto affiXed-my signature in presence of two witnesses.

JAMES H. TOWNLEY.
